BGA

Group Administrators: 1 | Group Member: 96 | Group Threads: 97

A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just the perimeter.

All,
I have an intermittent faut with a 672 BGA where it fails in test but upon applying pressure to the BGA it works.
Clearly there is an issue with the wetting of some Balls causing a poor connection.
My profile looks spot on -
I think I posted this before but never really came to any conclusion ..
What tests can I get carried out to pinpoint the problem?
